Effects of environmental enrichment on blood glucose and FINS in DD rats. (A) Timeline of the experimental procedure. (B) Schematic representation of the environmental enrichment protocol. (D) Comparison of random blood glucose levels among the four groups of rats. (C) Comparison of serum FINS levels among the four groups of rats. Data are presented as mean ± standard deviation, with 6 rats per group. Statistical analysis was performed using ANOVA. ###P < 0.001 compared to the control group. **P < 0.01 compared to the DD group. ***P < 0.001 compared to the DD group.
